Welcome back to the third week of the A-line skirt sewalong! This week, we’re going to insert the zip and finish the second side seam. Invisible zips are the easiest to insert because any little wobbles are, well, invisible. Lay out your skirt right side out, so that the unattached edges B and D are on centred and on the top. The back of the skirt (piece 2) will be on the left and the front (piece 1) on the right. You can see this in the photo below.
Now lay your zip, with the invisible side (teeth hidden) facing down, at the top of edge D. Line up the top of the actual zip (not the extra tape at the top) with the top of the waistband. Line up the teeth of the zip with the sewing line of D. Pin into place. Remember to fold down and pin the protruding top end of the zip, too. In the photo below, I have pinned the zip into place but haven’t folded the top of the zip down yet.
Now, this next bit is crucial. It takes a bit of time but saves a lot more time with a seam ripper later on. Hand sew the zip into place. Use medium sized stitches. Doing this means that you’ll sew it in neatly and accurately when you get to the machine. Then remove the pins. Unzip the zip all the way, taking care not to inadvertently pull the zip-pull right off the end, or your zip will be useless.
Fix your zipper foot to the machine. The key to inserting an invisible zip invisibly is to sew as close as possible to the teeth, by actually rolling them out of the way as you sew. In the photo below, I’m pulling the teeth out of the way. The point of the pin shows you how close I’ll get to the teeth. You can achieve a really neat job if you go slowly and carefully. Your basting stitches will stop everything shifting about, so you can focus on getting as close to those teeth as possible. Stitch the zip into place from the top to the bottom. The zip pull will stop you from being able to get all the way to the bottom; just do your best. Remember to backstitch at either end.
Now you’re going to sew the other side of the zipper to the front of the skirt. Press the seam allowance of edge B towards the wrong side, so that you have a crease where the sewing line is. Lay the skirt wrong side out this time, but still with edges B and D on top. Piece 1 (the front) will be on the left and piece 2 (the back) on the right.
Zip up the zip. Mark the point where you stopped sewing on the other side of the zip, with a fabric marker or pen. (This will be the point where you couldn’t get any closer to the bottom of the zip, because the zip-pull was in the way.)
Arrange the zip so that the unsewn side of it is invisible side (teeth hidden) down on the seam allowance of B. Making sure that the tops of both ends of the waistbands line up nicely, pin it to the top of the waistband. Don’t worry about folding the top of the zip over at this stage.
Then unzip the zip again. Aligning the teeth to the sewing edge of B, pin it into place from top to bottom. Make sure that you only pin the zip to the seam allowance, and not the outside of the skirt.
Check that you’ve positioned the zip correctly by arranging the skirt pieces as if they were all sewn up. The zip should be enclosed within the skirt, with the pull on the outside. If it’s incorrect, now’s the time to change it. If it’s correct, fold down the top of the zip, and hand sew the zip into place. Remove all the pins as you go. Zip it up and down again, just to check that everything is nicely aligned.
Using the machine, sew it into place, just as you did for the other side of the zip. Take your time and get as close to the teeth as you can. Stop when you reach the mark you made.
Now zip up the zip and turn your skirt inside out. Pushing the unsewn bottom part of the zip up and out of the way, insert a pin to hold the seam BD together along the sewing line. You can see that I’ve done this in the photo below. The pin needs to go as close as possible to the bottom of the stitched down portion of the zip.
Pin the rest of seam BD along the sewing line. Sew this seam, from as close you can get from the bottom of the zip all the way to edge E, making the join as smooth as possible. It should look like this from the right side:
Then turn it inside out and press the seam open. By now, it should be looking nice and neat.
That’s it! The zip and second side seam are done! Next time, you’ll finish the hem of your skirt.
Have you inserted an invisible zip before? What about other types of zip? Or have you been wary of them in the past?
